To all wlwmw'fmiiy cohcem:

Be it known that I, CLIFTON CHIsHoLM, a citizen of the United States,-residing at- Cleveland, in the county of 'Cuyahoga and 5 State of Ohio, have invented certaln new and useful Improvements in Embossing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to a method of and apparatus for producing embossed printing strips. The method is concerned with production of such a strip which has flanged edges so that it may I able holder. My invention includes also a stri -soproduced. The apparatus which may.v employed in carrying out this method and producing this strip comprises a keyboardcontrolled machine for emboss- 2 ing printing characters on a suitable strip or sheet, the object being to provide an efficient mechanism of this character which may berapidly operated to produce the desired product. i

My invention'includes areciprocable carrier or die head car ing male and female (lies with different 0 aracters, a keyboard having keys corres onding to the die char- Y acters and suitab e intermediate mechanisms, whereby upon the actuation of any key the die head is moved to bring the corresponding dies' to the embossing position andthereafter the embossing operation follows automatically. I

In its preferred form, my machine includes also means for feeding a ribbon of metal from a roll thereof and automatically fianging the edges thereof to give it a channel shape, and then to bring it into pos1t1on between the embossing dies and after the flanged strip is embossed to shearit into selective lengths and to bend inwardly the edges of the strip, whereby lines are produced suitablefor mounting on a holder, as for example, an address printing device.

I prefer to effect the reciprocation of the die head by electro-magnetic action controlled by the keys, there being preferably two magnets adapted to move the dle head froma central position in opposite directions respectively, the depression of half of the keys serving to energize one magnet,

be mounted on a suitand the depression of' the other half to energize the other magnet.

Another feature" of my invention is the combination with the keyboard and embossing mechanism, of printing mechanism adapted to print on a record characters corresponding to those embossed, such printing action being preferably visible during the operation.

My inventionjincludes, in addition to the above, numerous features contributing to the operation of the complete machine, allof which will be hereinafter more fully ex plained in connection with the. drawings, which illustrate a preferred embodiment of the invention. 1- 'will now describe such embodiment under the following headings:

General arrangement.

The frame of my machine is shown as consisting primarily of a horizontal bed plate 11, (Figs. 1, 2, 3 and 32) mounted on suitable legs 11. Numerous standards or brackets are mounted on this bed plate, as will be described hereinafter in connection with the particular mechanisms they carry.

Referring briefly to the general arrangement of the more important mechanisms of the machine, the keyboard 20, Fig. 1, is located at the front of the machine above an extension 13 of the bed plate, this keyboard consisting of suitable fingerpieces and rearwardly extendin levers 21, as hereinafter described. fit is the reciprocating die head 30, mounted to move laterally in either direction from -a central. postion, and carrying die blocks in cooperating pairs slidable towardandfrom each other, and having respectively male and female dies on their adjacent ends.

Near the end of the machine are two solenoid magnets which operate a core bar 61 to move the die head by linkage hereinafter desciiibed. lihe actuation of the key levers energizes one or; other of thesolenoid magnets, by means hereinafter described, to operate the core bar to shift the die head, and the raised rear ends of the key levers serve as stops for the die head, whereby it is caused to assume a position which will bring dies, corresponding to the character key depressed, into the embossing position, which is the center of the machine.

The die head becomes automatically locked in its selected position, and the positioned dies are forced toward each other to emboss an intermediate stri by means of levers 95 and 96, Fig. 2, which are operated by cams 93 and 94 on a shaft 91, the operation of this shaft being automatically initiated when the die head comes to position,-the positioning of the die head releasing a clutch which gives one rotation to the shaft 91. The material to be embossed is preferably a strip supplied as a coiled ribbon in a reel 248, Fig. 1, and fed fromthis reel on edge transversely of the machine by feed rolls, indicated at 250 and 251. These same rolls bring the ribbon into a channel shape, as hereinafter described, and after the emboss-
